Navigating Real-Time Challenges: Migrating Xamarin.Forms Projects to .NET MAUI | Community Feed

The migration guide gets the project building. Himanshu Tyagi writes about what broke after that, on a real Xamarin.Forms app, once the screens were running under .NET MAUI.

What you’ll learn

Layout options that disappeared — StartAndExpand, CenterAndExpand, EndAndExpand, and FillAndExpand are gone. What remains is Start, Center, End, and Fill, and the XAML has to be rearranged around that
Grids and stacks — rows and columns must be declared. StackLayout children can extend past the space they used to be clipped to, which is why he replaced many stacks with grids
Spacing defaults — padding, margin, StackLayout.Spacing, and grid row and column spacing default to zero, so screens that relied on the old defaults collapse
WebClient — deprecated from .NET 6. HttpClient covered his downloads. FTP does not, and needs another library
The UI thread — Device.BeginInvokeOnMainThread is deprecated in favour of MainThread.BeginInvokeOnMainThread

Read the post if your migration compiles and the UI still looks wrong. These are the differences he had to fix by hand.
